Hello @ElizabethB373 ,
Without seeing exactly what was used within the email, I would have to guess they used an animated GIF image. An animated GIF is a series of still images that have been strung together to create continuous movement - like a flip book. There are many tools, like Adobe Photoshop or online GIF creators, which can help you create the perfect animation for your email's purpose. You can also purchase animated GIFs from various sources online. These are able to be uploaded into the library the same as you do with any other still images. I have attached more information about GIFs and how to effectively use them here for you.
Please be advised that Constant Contact employees are not trained in the creation process of GIFs using third party software. If you run into any issues during creation you would need to contact the support staff for that service you are using to create it.
